RAID 2 recovery is the process of recovering and restoring data in a RAID 2 infrastructure.
It includes both automated and manual measures that enable a RAID 2-type array to recover to its normal working operations and restore any data.
Techopedia Explains RAID 2 Recovery
RAID 2 recovery is usually performed through RAID recovery software that scans each drive or array for corrupted or deleted data or hamming parity information. Typically, RAID 2 recovery requires recovering hamming code parity to restore data in the correct parity order. This information is stored on one or more parity drives. If the drives installed within the array suffered a physical problem such as head crash or spindle problem, it must be physically replaced before operation can be restored on the RAID.
